QMSR: Qos Multi-hop Sensor Routing Cross-Layer Design for WSNs

Abstract

We have proposed a QoS Multi-hop Sensor Routing (QMSR) protocol that is developed for Mobile Wireless Sensor Networks (MWSNs). This protocol manages Admission Control Scheme (ACS) with minimum overhead resources for fresh flows without degrading the performance of the existing flows. ACS is an important strategy for regulating the parallel flows in a contention-based channels to meet the requirements of QoS. QMSR estimates the available bandwidth before allocating the resources on a per hop basis. The protocol minimizes the overall energy consumption and guarantees the end-to-end delay
